SIDE FRAME.

Specification of Letters Patent. Patented J l 20 1915 Application filed April 22, 1915. Serial No. 23,030.

To all v 'li am it may concern Be it known that I, JOHN A. LAMONT, a

citizen of the United States, and resident of Granite City, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Side Frames, of which the following is a'specification.

My invention relates to railway cars, and has'partic'ular reference to a novel built-up side frame for use in connection with car trucks.

An object in the construction of the present device is to provide for economy in cost of construction. This economy is the result of the use of commercial rolled sections which are fabricated. to form asubstantially integral side frame structure.

A further object is to lessen the weight of such structures by so disposing the metal thereof that the greatest possible resistance is secured with minimum weight. In the present structure the principal parts of the truss, namelythe compression and tension members, are formed from commercial rolled shapes, the remainder of the parts being formed by casting in steel or malleable iron.

The invention will be more readily understood by reference to the accompanying drawings, wherein Figure 1 is a side elevation of a portion of a side frame constructed in accordance with my invention, Fig. 2 is a plan view thereof,

with the top or compression member partially broken away, Fig. 3 is a similar plan view showing the parts in their assembled relation, Fig. 4 is a view similar to Fig. 1, showing a. slightly modified construction, Fig. 5 is a plan view of the construction shown in Fig. -l, with the compression member. broken away, and Fig. (3 is a fragmen tary elevation partly in section showing a further modification.

Referring more particularly to Figs. 1, 2 and 3, it will be seen that I provide a compression member 7 shape, a tension member 11 of T-shape, and a strut member 12 in the form of a casting. The ends of the compression and tension members are tied together by the use of a casting 13. I

The compression member, as stated, is in the form 01 a channel, and at the ends thereof the web His continued beyond the termination of the" flanges, forming a tongue or extension which is bent downwardly, as later described.

10 of generally channel The strut member is so formed as to provide colhmns having bolster guides 15 and a spring seat 16, the space between the two columns being enlarged at the point 11'' to permit the insertion of a bolster having side lips or flanges. The upper portion oi the strut member 1; is .+rovidc l with a con necting web 18 which is: riveted to the chair nel compression member.

The T-shaped tension member is in ert: within a similarly shaped aperture in t? e casting 13, the flange of the member being terminated at the point 19 in Fig. 1, the remaining portion 20 of the member continuing past the sheared off end of the flange and being bent downward into engagement with the casting 13. the lip 14 of the compression member and said extension 20 of the'tension member being secured to the casting by rivets 21.

The casting which unites the ends of the truss is provided with an upwardly extend- ;ing filler or brace portion 22 which lies between the tension and compression members and is secured to the web of the compression member by means of the rivets 2 The casting is preferably in the form of a pedestal providing jaws 24, 25 between which a journal-box 26 may be held.

In the construction shown in Figs. and

5, the tension and compression members do not actually come in contact. The compression member 2,7 is formed from a couuncr channel shape. the metal flanges of thechannel being suitably shearc oil and terminating at the point 3;. theremain'ing portion of the member continuing and being bent dowmvard, as at -H. a rivet 33 sceuring this portion'to the casting. The tension mcmber accommodatcd within a properly and is secured shaped recess in the casting thereto by means of rivets ll. The strut member 37 is similaiyto that described in connection with Figs. l.to

In Fig. ('1 the compression member 39 is of rolled channel form. the flanges thereof bcing terminated short of the, end. leaving the web 40 to continue onward and abutting against a shoulder 41 on the castingi'i. 'l be In each case it will be seen that the parts,

tension member of channel shape. its

side flanges being cut oihthe web it of the member continuing on andbeing bent downward 1nto a recess or notch i5 111 the cast 5 ing. In this case I have shown the 'joun" nal-box as integral with the casting, it be mg understood thattlns1s-.an alternative construction with relation to allot the forms,

shown.

when assembled aiitla-ivetetl. formfla sub- .stant ally integral structure. thed sposition of metal being such that the greatest resistance to strains is secured with the least weight. Furtl1ermore, it will be understood that the rolled shapes emplovedlend them-, selves readilv to the formation ofa truss ed onto the end of the tension .member and.

that thereafter the end of the tensionmember is bent downward. preferably while hot,

int-o itsgfinal position.

It will be understood thatwherever I have referred to the use of rolled shapes-that pressed shapes mightbe used witlrequal,

facility and that therefore l consider the terms rolled and pressed as synonymous. I claim:

1. In a side frame, the combination oftension member. compression member and strut, and a castinginthe form of a journal box pedestal within which the end of 3 said tension member is fitted and against which said compression member-abuts. and
